What comes in the box?
These W201 windows are 4.5mm (.177") thick. Factory glass windows are 3.2mm thick, but we designed these to be 4.5 millimeters thick due to the FIA specifying an absolute MINIMUM thickness of 4mm for Lexan windows. You might need to sand edges down if your motor is weak and cannot push the thicker window up in the seal.
Please Note: Windows will arrive with backing on them that must be peeled off. We recomend that you do not remove until you install on car! Otherwise you risk scratching them on install.
NOTE: Rear triangle windows do not require any modification and should slide into place as the OEM window does
The #1 Problem we see is the use of incorrect cleaners. Never, ever, use cleaners containing ammonia. Cleaners such as Windex or 409 will harm your new windows!
Never use a dry cloth or your hand to clean your polycarbonate! This rubs the dirt and dust INTO the polycarbonate as much as it rubs it OFF.
How To Clean
The #2 Problem with polycarbonate is Sunlight!
Windows are good for 3-5 years if you leave your car in direct sun! It will start to haze and discolor a bit. It does not lose its strength but is less transparent. This is something that happens to all Lexan windows! Don't be an animal! Cover or put your beloved Mercedes inside!
